    • Preservative compositions, their methods of manufacture, and use in preserving timber and other substrates. The compositions of the invention have unique modes of intra-component interaction and substrate- preservative- atmosphere interaction. More particularly, the invention relates to creosote based emulsions and derivatives, hereinafter referred to as pigment emulsified creosote (PEC). In accordance with the invention there is provided a preservative composition which is ultra-stable in the presence of wood extractives, said composition comprising an emulsion of a wood preservative grade creosote, from 5 to 95% water, and one or more pre-dispersed micronised pigments, said emulsion having been produced under conditions of ultra high shear, characterised in that said composition contains from a trace to 2.5 wt% of a rheology structuring agent, from 0.25 to 10 wt% of an alkali metal salt of a wood derived resin, from 0.1 to 5 wt% of a surfactant, from 0.25 to 5 wt% of a lignin sulfonate and from 0.25 to 2 wt% of a pigment modifying resin, said percentages being based on the total weight of said emulsion.
    • 防腐剂组合物,其制造方法和用于保存木材和其他基材。 本发明的组合物具有独特的组分间相互作用和底物 - 防腐 - 大气相互作用的模式。 更具体地,本发明涉及基于杂酚油的乳液和衍生物,以下称为颜料乳化杂酚油(PEC)。 根据本发明,提供一种防腐组合物,其在木材提取物存在下是超稳定的,所述组合物包含木材防腐级杂酚油的乳液,5至95%的水和一种或多种预分散的微粉化 颜料,所述乳液已经在超高剪切条件下制备,其特征在于所述组合物含有痕量至2.5重量%的流变结构剂,0.25至10重量%的木衍生树脂的碱金属盐, 0.1至5重量%的表面活性剂,0.25至5重量%的木质素磺酸盐和0.25至2重量%的颜料改性树脂,所述百分比基于所述乳液的总重量。
